12) Unplug this apparatus during lightning storms or when unused for long periods of time.

13) Refer all servicing to qualified service personnel. Servicing is required when the apparatus has been damaged in any way, such as power-

supply cord or plug is damaged, liquid has been spilled or objects have fallen into the apparatus, the apparatus has been exposed to rain or

moisture, does not operate normally, or has been dropped.

WARNING - To reduce the risk of fire or electric shock, do not expose this apparatus to rain or moisture.

Foreword

Thank you for purchasing the Ibanez TA20 acoustic guitar amplifier.

Read this manual thoroughly prior to using your amplifier in order to get the most out of the functions available. Ensure that this manual is also stored in a safe place.

Features

The TA20 amplifier provides 20W of output and is mounted with 8-inch woofer and tweeter Ibanez original speakers. The EQ employs bass and treble and a variable

parametric EQ in the middle to produce a wide range of sound. Moreover, the speed and depth of the chorus effect (turned ON/OFF by switch) can be controlled. The TA20

is also equipped with a built-in variable level reverberation function to bring out the depth of sound.

Precautions During Use

• Do not subject the amplifier to shocks by dropping or rough handling.

• Install the amplifier in a stable location. The amplifier will sound differently depending on the method, location or venue of installation.

• Ensure that the power supply is switched OFF when the amplifier is not in use. Also remove the power cable from the power supply socket when the amplifier is not to be

used for an extended period of time.

• Do not use or store the amplifier in locations where it is subject to direct sunlight or in environments that experience dramatic fluctuations in temperature and humidity

levels.

• Reduce the volume to “0” or switch OFF the power supply when connecting the guitar shielded cable, and cables connected to external units, such as the effects. Note that

the noise generated when plugs are inserted or removed may cause severe damage to the equipment.

• To avoid the danger of fire, do not place containers of liquid on the amp.

1. INPUT jack

This is the input jack for standard 1/4" plug. Connect from the guitar using a

shield guitar cable.

2. DGUITAR-VOLUME control

This controls the output of the guitar pre-amp section. Noise is best controlled by

increasing the guitar volume and lowering the amplifier volume rather than the

reverse. Lower this volume if distortion occurs because the volume of the guitar

is too loud or the EQ is set too high.

3. BASS control

This is a shelving-type equalizer that lets you boost or cut the region below 70 Hz

by ±15 dB.

4. MIDDLE FREQ. control

This can vary the frequency boosted or cut by the MIDDLE LEVEL control in the

range of 400Hz to 2kHz.

5. MIDDLE LEVEL control

This can boost or cut the frequency bandwidth set at the MIDDLE FREQ. control

by ±15dB.

6. TREBLE control

This is a shelving-type equalizer that lets you boost or cut the region above 8.7

kHz by ±15dB.

7. CHORUS-DEPTH control

This adjusts the depth of the chorus effect. Turning the control toward the right

will deepen the effect.

8. CHORUS switch

This is the ON/OFF switch for the chorus effect.

9. CHORUS-SPEED control

This controls the ripple speed of the chorus effect. Turn this control to the right to

increase the speed.

10. REVERB-LEVEL control

The TA20 is equipped with a spring reverberation function. Use this level control

to adjust the amount of reverberation to be applied. A natural depth to the sound

output is achieved by applying reverberation.

11. POWER switch

This is the switch to turn the power supply ON and OFF. Be sure to turn this

power switch OFF when the amplifier is not in use.

12. FUSE holder

If the fuse has blown, it is possible that a serious internal malfunction has oc-

curred. Please contact your dealer before you replace the fuse.

13. AC inlet

Connect the included AC power cable to this connector. Never connect the amp

to a voltage other than the input voltage printed on the panel.

14. LINE OUT jack

This is an output jack with a level of approximately 0 dBm. You can connect it to

an external mixing console or other device.

15. SPEAKER OUTPUT jack

This is the output jack to the speaker; it is connected to the built-in speaker

system.

Troubleshooting

1. The power supply cannot be switched ON.

• Check that the power cable has been connected correctly.

• Try plugging it into a different power supply socket and see if the same problem occurs.

2. The power supply can be turned ON, but no sound is produced.

• Check that the guitar has been connected correctly.

• Remove the effects between the guitar and the amplifier and check to see if no sound is produced.

• Replace the shielded cable and check to see if no sound is produced.

• Check to see if the volume on the guitar is set to “0”.

• Check to see if there are batteries in the guitar. If there are, check that they are OK.

• Use a different guitar and see if no sound is produced.

• Check to see if the volume on the amp is set to “0”.

3. Noise occurs

• Check to see if anything in the immediate vicinity is resonating or banging against the amplifier to produce the noise.

• Check to see if the plug cover on the shielded cable is loose.

• Check that the string action (distance between strings and frets) is correctly adjusted (not too low).

• Check to see if the guitar batteries are depleted.

• Use another guitar, effects and cable to see if the same noise is produced.

In the case of defects

This product has passed exhaustive inspections before being shipped from the factory. Ensure that the above procedures are carried out when a problem is thought to exist.

Contact your dealer in the unlikely event that an abnormality occurs during use. Also, ensure that the symptoms of the problem are explained in detail when requesting repairs
